In 1990, a homeless street musician by the name of Mark Bittner found himself being drawn in by a flock of 26 wild conures that inhabited San Francisco’s Telegraph Hill. It started with a little curiosity, but with time and patience, Mark found the birds eating out of his hands. When he first noticed them in 1990, there were 26 birds, mostly Cherry-Headed Conures (Aratinga erythrogenys), but as breeding seasons passed, the flock grew, to an estimated 160 today.
